It accepts voltage, current, T/C, and RTD signals across 4 inputs, letting one slot cover a mixed temperature and process panel without extra signal conditioning. ## Lifecycle: this is the line that matters The CJ1W-PH41U is flagged at lifecycle stage eol_hot, which is the only thing that should drive the procurement decision for a line-down or new-build spec today. ## What to verify before you write the PO For the field-side wiring, the I/O and relay terminations land on screw terminals, so strip length and torque follow the standard Phoenix-style cage practice used across the CJ I/O family — worth a quick check against the panel's existing terminal marking before the wireman commits to gland plate cutouts. The 2 MOS FET outputs are solid-state, not mechanical relays, so they switch quietly and have no contact bounce, but they also do not carry the inrush of a mechanical contactor output — any plan to drive a solenoid or lamp load directly should be re-checked against the MOS FET output's on-state rating before sign-off.","metaTitle":"Omron CJ1W-PH41U Analog I/O, 4 ch, 2 MOS FET, EOL","metaDescription":"Omron CJ1W-PH41U CJ-series analog I/O unit, 4 inputs supporting V/mA/T/C/RTD, 2 MOS FET outputs, 0.0005 accuracy at 25 °C.
